From what I've seen you can get Bushmaster, RRA, Stag, DPMS, Windham, Daniel Defense.
There are others but cant remember off the top off my head.
Firearm prices in general are a lot higher than the US though, and ammo too.
If you want a rifle that can take a 30round mag, it comes into another category which then generally makes them cost more again.
The 53gr Vmax's look very good, the BC is surprisingly high for light .224 bullets, and I've heard of some very quick velocities from them too.
